Learning how to drive a shifter kart correctly could be very difficult to start with, as you’re constantly multi tasking so quickly and it is very exhausting, once you get smooth and good at it, they are a blast to drive, there is no other thrill close to it, other than Indy cars and F1 cars.
That’s why I asked all those questions
There are other classes to start with, that have less HP, but yet tons of fun to drive, and very good racing/competition. And usually enables you how to concentrate on your driving skills, rather than tuning, and multi tasking.
LO206 is a great option for the money, here’s a video at the same track with LO206 karts, those guys look like they’re having lots of fun, and it’s really cheap to run and maintain.
